I believe the tail end of remote_target::mourn_inferior is broken, and
it's been broken for too long to even bother trying to fix. Most
probably nobody needs it. If the code is reached and we find the
target is running, we'd need to resync the thread list, at least,
since generic_mourn_inferior got rid of all the threads in the
inferior, otherwise, we'd hit an assertion on the next call to
inferior_thread(), for example. A "correct" fix would probably
involve restarting the whole remote_target::start_remote requence,
exactly as if we had completely disconnected and reconnected from
scratch.
Note that regular stub debugging usually uses plain target remote, but
this code is only reachable in target extended-mode:
- The !remote_multi_process_p check means that it's only reacheable if
the stub does not support multi-process. I.e., there can only ever
be one live process.
- remote_target::mourn_inferior has this at the top:
/* In 'target remote' mode with one inferior, we close the connection. */
if (!rs->extended && number_of_live_inferiors () <= 1)
{
unpush_target (this);
/* remote_close takes care of doing most of the clean up. */
generic_mourn_inferior ();
return;
}
Which means that if we only had one live inferior (which for our
case, must be true), we'll have closed the connection already,
unless we're in extended-remote mode.

* remote.c (remote_target::mourn_inferior): No longer check
whether the target is running.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
